Here’s the couch that catapulted a career.

This ordinary sofa could become the most famous piece of furniture in sports — as the impromptu sleeping place that Knick phenom Jeremy Lin crashed on in his teammate’s Manhattan pad the night before his breakout game.

Knick guard Landry Fields satisfied the ravenous interest of couch potatoes swept up in the Linsanity by tweeting a picture of the artifact.

“Ladies and gentlemen, the one and only couch made famous by @JLin7!” Fields tweeted at around 4 p.m.

“Let the bidding begin,” he quipped.

After Lin got off the couch — and the Knick bench — he scored 25 points against the Nets on Feb. 4.

The former Harvard University player went on to become a starter — and an instant fan favorite by leading the Knicks on a five-game winning streak.

Fields is not the only one who can post a historical marker that reads: “Jeremy Lin slept here.’’ Until he moved to Fields’ sofa, the nomadic Lin had been crashing on the couch in his brother’s Lower East Side apartment.

But when he came home from a game in Boston two Fridays ago, Lin found himself displaced because his brother, Joshua, was hosting a party.

So the 6-foot-3 point guard landed on his teammate’s sofa — described by Fields as “decent but not huge’’ — and went from unknown to superstar in the course of a week.

“Thank you to Landry for hosting me,” Lin said after his career-best performance against the Nets on Saturday. “I think I might just move in with him.”

Since then, he has been shopping around for more permanent digs. He’s looking at an apartment in the city owned by a teammate, as well as at a Westchester pad.

Meanwhile, attorney and real- estate developer Edward Mermelstein has offered Lin a one-bedroom apartment free until he can find his own.

Mermelstein, an avid Knicks fan who has courtside seats, said, “It’s very rare that someone like Jeremy Lin comes along to electrify this city, and this humble young man has excited all off New York City.”
